EMERY ANDRIHVS, OF KENNEBUNK, MAINE, ASSIGNOR TO THE MOUSAMMANUFACTURING COMPANY, OF SAME PLACE.

MACHINE FOR FORMING HEEL-STlFFENERS.

SPECIFICATION forming part of Letters Patent No. 371,537, dated October18, 1887 Application filed February 17, 1887. Serial No. 227,915. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, EMERY ANDREWs, of Kennebunk, in the county of Yorkand State of Maine, have invented certain new and useful Improvements inMachines for Forming Heel-Stiffeners, of which the following, taken inconnection with the accompanying drawings, is a specification.

My invention relates to machines for forming heel-stiffeners to thedesired shape to fit the heel portion of the last, and particularly tothat class of such machines in which a divided or sectional mold isused; and it con sists in certain novel features of construction,arrangement, combination, and operation of parts, which will be readilyunderstood by reference to the description of the drawings and to theclaims to be hereinafter given.

Figure l of the drawings is a plan of a ma chine embodying my inventionwith the flangeturner and its support removed. Fig. 2 is a front endelevation of the same with aportion of the legs broken away. Fig. 3 is avertical longitudinal sectional elevation, the cuttingplane being online m m on Figs. 1 and 2; and Fig. 4 is a partial plan with the moldclosed upon the blank and in position to commence to turn the flange.

In the drawings, A is the bed of the machine, supported by the legs A,and provided upon its upper side with ways to receive the reciprocatingcarriages B and B, and with the side cheeks, C C, upon the upper edgesof which are secured the boxes I; b, in which are mounted the shafts Dand D, respectively.

The shaft D has firmly secured upon one end thereof the driving-pulleyD, and upon the other end the pinion D which meshes into and impartsmotion to the gear-wheel D, firmly secured upon the shaft D, which shafthas also secured upon its opposite ends the crank-disks c c, in each ofwhich is set a crankpin, d, upon which is fitted one end oftheconnecting-rod E, the opposite end of which is fitted to ajournal formedupon the end of the bar F, firmly bolted to the upper side of thecarriage B, as clearly shown in Figs. 1 and 2.

The carriage B has firmly secured upon its upper side the heel-shapedformer G, and the carriage B has firmly secured thereon the centralsection, H, of the stiffener-forming mold,

The carriage B has pivoted to its uppersur face the two arms I and I, inthe forward end portions of which are formed concavities e, shaped toform counterparts of the side portions of the heel-shaped former G, asshown in Fig. 1. the arms J and J, respectively, each carrying in itsfront end an anti-friction roll, f, and adjustable toward and from thearm I or I by means of the screw 9 and check-nut h, as shown in Figs. 1and 2.

To the inner faces of the cheeks C C, at their forward ends, are securedthe plates L L, having their inner vertical surfaces at their front endscam shaped, as shown at 11 t in Fig. 1, against which the rolls f f bearwhen the carriage B is at the extreme of its forward movement, and thearms I and I are forced apart by the reaction of the spring M, as shownin Fig. 1.

N is a plate or bar extending across the ma chine from one cheek C tothe other, above the stiffener-forming sectional mold, the same beingfirmly secured at its ends to the upper edges of the cheeks C C bysuitable bolts, as shown.

0 is the flange-turning plate, having formed in its front end theV-shaped notch j, and being suspended from the plate or bar N by thescrews 7; k, which are fitted to threaded holes in the plate N andconnected to the plate 0 by a swivel attachment in such amanner that theplate 0 may be adjusted vertically by turning the screws 7a 7a in anobvious manner.

The carriage B is moved toward the front end of the machine, or towardthe left-hand end of Fig. 3, by means of the weight P, at tached to oneend of the cord Z, which, after passing over the pulley m, has its otherend attached to the eyebolt a, screwed into the under side of thecarriage B,near its rear end, the forward movement of said carriage Bbeing arrested at the proper point by the pin 0, set in the under sideof said carriage, coming in contact with a pin, 19, set in the bed A,all as shown in Fig. 3.

The operation of my invention is as follows:

To the arms I and I are pivoted The several parts being in the positionsshown in Figs. 1 and 3 of the drawings, a stiffenerblank is placed bythe operator between the rear end of the former G and the front ends ofthe side sections of the mold, with its straight edge uppermost andprojecting above the upper surface of the former a distance equal to thewidth of flange that it is desired to have formed upon the stiffener,and with the center of the length of the blank coinciding with dottedline .70 w, in which position it is held until, by the rotation of theshaft D and crank-disks c, the former G has moved. toward the rear asuflicient distance to press the blank into the curve of the front endof the central section, H, of the divided mold, and firmly clamp saidblank between said central section of the mold and the rear end ofthe-former, when acontinuation of the rearward motion of the carriage Band the former G causes a corresponding rearward movement of thecarriage B and the divided or sectional mold attached thereto, and bythe rearward movement of the rolls f f along the curved surfaces t ofthe plates L L the side sections, 6 e, of the mold are closed upon theblank to press ithard upon the former G, as shown in Fig. 4. A furthercontinuation of the rearward motion of the carriages B and B, carryingtherewith the former and mold, with the blank clamped between them,causes the portion of the blank which projects above the upper surfacesof the former and mold to be turned inward upon the upper surfaceof saidformer and pressed hard thereon to form the heel seat or flange of thestiffener by the action thereon of the V-shaped front end of thestationary flange-turning plate 0. When the former is returning to theposition shown in Figs. 1 and 3, after having completed the forming of aheel-stift'ener,and when it has nearly reached the extreme of itsforward movement, the stiffener is removed from said former and anotherblank is placed in position to be formed by the next rearward movementof said former.

The cam-plates L t have inserted between them and the checks 0 0 sheetsof rubber r, so as to render them slightly yielding to compensate forslight variations in the thickness of different blanks in the samelot orin differ ent parts of the same blank.

Above the end portions of the plate N, and between it and caps N, areplaced pieces of rubber s, so as to render said plate N and theflange-turning plate 0 slightly yielding when the pressure is increasedbeyond a given point by inequalities in the thickness of the stock, therubber pieces 1* and s all being compressed to the proper degree oftension to resist any desired pressure without yielding by the bolts 1"and s', respectivelyybut if by an increased thickness of the stock inany part the pressure is increased beyond said desired or predeterminedpressurethe camplates Lt or the plates N andO will yield sufficiently toprevent injury to the blank.

What -I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. The combination of a reciprocating heelshaped last or former, asectional mold composed of three parts, two of which are movable towardand from each other and relative to the third or central part, and'allof the parts of said sectional mold being movable by and with saidformer during a portion of its reciprocation, a stationary flangeturningplate having a notched operating end, and mechanism, substantially asdescribed, for reciprocating said former and closing the side sectionsof the mold upon the former.
